Although adriamycin (ADR) is used to treat many cancers, it can be toxic to healthy organs including the testis. We investigated the effects of ADR on pluripotency in rat testis. Testicular damage was induced by either cumulative or single dose single dose administration of ADR in Wistar albino rats. Rats were divided randomly into three groups: untreated control, cumulative dose ADR group (2 mg/kg ADR every three days for 30 days) and single dose ADR group (15 mg/kg, single dose ADR). Testicular damage was evaluated and seminiferous tubule diameters were measured using light microscopy. Expression levels of Oct4, Sox2, Klf4, c-Myc, Utf1 and Dazl were assessed by immunohistochemistry and real time PCR. Serum testosterone levels were measured using ELISA assay. Histopathologic scores were lower and mean seminiferous tubule diameters were less compared to the ADR groups. Oct4, Sox2, Klf4 and Utf1 expressions were decreased significantly in spermatogenic cells of both cumulative and single dose ADR groups compared to the control group. We found that c-Myc expression in spermatogenic and Leydig cells were increased significantly in both ADR groups compared to the control group. Dazl expression was decreased in the cumulative adriamycin group compared to the control group, but increased in the single dose ADR group compared to both the control and cumulative ADR groups. Serum testosterone levels were decreased in both ADR groups compared to the control group. Our findings suggest that ADR is detrimental to regulation and maintenance of pluripotency in rat testis.
